rmvb

rmvb(9F)						   Kernel Functions for Drivers 						  rmvb(9F)

NAME

       rmvb - remove a message block from a message

SYNOPSIS

       #include <sys/stream.h>

       mblk_t *rmvb(mblk_t *mp, mblk_t *bp);

INTERFACE LEVEL

       Architecture independent level 1 (DDI/DKI).

PARAMETERS

       mp	Message from which a block is to be removed. mblk_t is an instance of the
		 msgb(9S) structure.

       bp	Message block to be removed.

DESCRIPTION

       rmvb()  removes	a  message  block  (bp) from a message (mp), and returns a pointer to the altered message. The message block is not freed,
       merely removed from the message. It is the module or driver's responsibility to free the message block.

RETURN VALUES

       If successful, a pointer to the message (minus the removed block) is returned. The pointer is  NULL if bp was the only block of the message
       before
	rmvb() was called. If the designated message block (bp) does not exist, -1 is returned.

CONTEXT

       rmvb() can be called from user or interrupt context.

EXAMPLES

       This  routine  removes  all zero-length M_DATA message blocks from the given message.  For each message block in the message, save the next
       message block (line 10). If the current message block is of type M_DATA and has no data in its buffer (line 11), then remove  it  from  the
       message (line 12) and free it (line 13). In either case, continue with the next message block in the message (line 16).

	1  void
	2  xxclean(mp)
	3      mblk_t *mp;
	4  {
	5	   mblk_t *tmp;
	6	   mblk_t *nmp;
	7
	8	   tmp = mp;
	9	   while (tmp) {
       10		    nmp = tmp->b_cont;
       11		    if ((tmp->b_datap->db_type == M_DATA) &&
				  (tmp->b_rptr == tmp->b_wptr)) {
       12			 (void) rmvb(mp, tmp);
       13			 freeb(tmp);
       14		    }
       15		    tmp = nmp;
       16	   }
       17  }
